Answer:
C. (14, 9)
Explanation:
The coordinates of the data are usually in the following order
(explanatory variable, response variable)
In this case, the explanatory variable is 14 and the response variable is 9, so the point will be
C. (14, 9)
I think it is b.............
Step-by-step explanation:
sin(A − B) = sin A cos B − cos A sin B
sin50°cos 40° - cos50°sin 40°
= sin(50-40)°
=sin10°
cos(A + B) = cos A cos B − sin A sin B
cos75°cos 15° - sin75°sin 15°
= cos(75+15)° = cos90° = 0
Answer:
Concept: Caclulating Standard Variables
- We have a five number summary which is more than enough information to calculate our mean.
- The mean is the sum of all the numbers divided by the nth number of numbers.
- Note that we can only find a rough estimation not the EXACT value
- We do (min +max + 2(Q1+median+Q3))/8
- Now let's plug in our values!
- (0+85.3+2(8.4+17.4+30.9))/8
- Which gives us option B
